its meant for putting a 3inch downpipe to mate with a stock catback or others that tapers to 2.5inch IE: cobb , um greedy? stromung etc....

i've put on a 3inch catback on the stock downpipe with no adapters the donut fits snug inside the 3inch midpipe , though some people buy a 3inch gasket to be extra secure....
